ISAAC OLVER, OF BINGHAMTON, NEW YORK.

'IEXTILE sPooL.

Ap plcation filed September Be it kn own that l, IsAAc OLlvnn, a citizen of the United States, residing at Binghamton, in the county of Broome and State of N ew York, have invented certain new and useful Improvements in Textile Spools: and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rllhis invention relates to textile spools or bobbins, and more particularly to a practically indestructible spool head.

Spool heads composed of thin layers or sheets of paste-board or paper and woodveneer, cemented together, and also heads composed of layers of rotary cut veneer, cemented together, have heretofore been made, and it also has been proposed to construct a spool head of vegetable bre. board, or a hardened composition of flax fibre, but such heads will not withstand the severe strains to which the heads of spools are subjected, in practical use, as the wood or paper is liable to chip or splinter, and the chipped or splintered surfaces present defects in textile use, for the fine strands of cotton, silk or other textiles will catch on these splinters and cause waste of material and diminished production.

Such heads are also liable to absorb moisture on coming in contact with any moisture conditions, even high humidity in the atmosphere, as the wood or paper absorbs moisture which causes the layers to become uncemented or unglued, in which case the spool goes to pieces almost immediately, and when such spools are stored in a dry storehouse and subjected to temperature changes they will absorb moisture which will cause them to warp and the cemented parts to se arate.

'lfhc objects of my invention are to overcome the defects of spool heads as heretofore proposed or constructed, and to provide a spool with heads that will not warp or twist, nor chip or splinter, when the head gets a knock or is subjected to severe strains, but will at all times wear smoothly and resist the severest strains to which spool heads are subjected without liability to chip or splinter or present other surface defects in textile use.

The i1 v'ention resides in a spool having fibre-cla heads composed of a core of wood 2, 1924. Serial No. 735,457.

or other suitable soft material secured to and between outer layers of hard vulcanized libre, which will not wear rough, nor splinter, nor chip, no matter how hard the usage to which the spool is put in ordinary mill wear; the several layers of wood and iibre beingsecured together by cement applied to thel contacting surfaces thereof and such securing means being reinforced by cementcoated nails or rivets inserted through the combined layers of wood and fibre.

The invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken' as a part of this specification. and then pointed out in the claims at the end of the description.

In said. drawings, Fig. 1 represents a spool having a wooden barrel with heads embodying my invention;

Fig. 2 is an end view of the spool showing a side elevation of the head at the left side of Fig. 1;

Fig. 8 is an end view of the spool showing a side elevation of the head at the right side of Fig. 1; and

Fig'. 4 is a vertical longitudinal sectional view of the spool, illustrating the construction of the heads and mode of securing them to the ends of the wooden barrel. i Referring to said drawings, in which the same reference letters are used to denote corresponding parts in different views, the letter A. denotes the barrel of the spool or bobbin, which consists preferably of a tubular or hollow cylindrical body of wood, to the ends of which are secured the heads B and B1, which are alike, except the peripheral portions thereof, one of which is beveled or rounded while the other has a straight edge, but they may be of any desired shape. Each head is composed preferably of two or more layers C, of wood secured together and to and between inner and outer layers D of hard vulcanized fibre, the two liayers of libre being glued or cemented to the intermediate layer or layers of wood, and also nailed or riveted thereto by means of a circular row of cement-coated nails or rivets inserted at or near the periphery of the head, whereby the heads of the spool are made indestructible in textile use. The heads are. secured to tapered bushings E inserted through central openings therein, by means such as are illustrated and described in Patent No. 1,515,148 granted fibre-clad Harry D. Clinton, November l1, 1924, for method or' and means for producing textile spools and bobbins, said bushings being inserted in the ends of the Wood barrel after applying thereto a suitable cement or other adhesive substance, whereby they are'firmly secured Within the ends of the barrel.

The head oit' any spool is always its Weakest feature. VIn a spool of the described construction the head is the strongest featiilre, as has been proved by actual tests, which is untrue of any other spool heretotore produced, and these heads-4 can never Warp, so as to become objectionable, as the hard libre on the outer sides of the Wooden core protects the inner layers of Wood and prevents them from absorbing any moisture Which would cause them to Warp. The use of 'the cemefntcoa'ted nails for securing the outside layers of hard vulcanized fibre and interposed layers of Wood together renders it practically impossible to extract the nails after they are driven in place, and the outer layers of hard fibre and intermedi-ate layers of Wood are prevented from becoming unglued or uncemented by reason of moisture conditions, or under varying conditions of use, and by reason of the outer layers of hard vulcanized fibre the head is to all intents and purposes indestructible in mill y use. v

said bushings having applied thereto a suitable adhesive substance and inserted in the ends of the barrel, whereby the heads are iirinly secured to the ends or' the barrel.

2. A textile spool having a tubular barrel of wood and a head composed of inner and outer layers of hard vulcanized libre and an intermediate layer or layers of Wood secured together by means oi a suitable cement applied to the contacting surfaces thereof, and reinforcing securing means consisting of series of cement-coated fastening devices inserted at or near the periphery of the head; said head having a bushing inserted. through a central opening therein and said bushing having applied thereto a suitable adhesive substance and inserted in the end of the barrel, whereby the tivo parts are firmly secured together.

3. A textile spool comprising a tubular barrel of wood having practically indestructible heads; said heads consisting of inner and outer disk-like layers of hard vulcanized iibie and intermediate layers of wood having cement applied to the contact ing surfaces thereof for securingr them together, and reinforcing 'securing means consisting of a series of Ieement-emited fastening devices inserted through the combined layers of the head at or near the periphery thereof; said heads having tubular bushings inserted through central openings therein, and said bushings having cement applied thereto and inserte-d in the ends of the barrel for securing the two parts together.

In testimony whereof I ailix my signature in the presence of two Witnesses.
